Dear Mike, dear all,
(Still if someone knows about the Speed Box S compatibility let me know!!)
You are 100% right. I have a better system in the other room and wanted to build a budget one for my small study, so I have there a $300 Onkyo musical centre, budget Atacama speaker stands, Ikea-produced furniture, a Cambridge Audio 640P phono stage, and of course the MMF 2.2. However (as Mike) I use a cork mat. (I must say, the humming noise started as I opened the box, when no changes were made yet! maybe I only noticed it thanks to my bigger and better system where "silent" parts on a record are really silent)
However, I could not resist
I replaced the platter with Acryl-It from Pro-Ject, and I replaced the cartridge with a (I had a used one) Benz Micro Silver. I also use a Van den Hul inter-component cord and some high-quality speaker cords, apart from that no extra....
I agree that the "stock" options (MM cart, metal platter) also sound OK but believe me, even on an Onkyo mini system, the MC (Benz) with the acryl platter give the sound the depth not achieved before....
Many thanks if someone knows about the Speed Box
Happy new year everyone!!
